Properties of mechanically alloyed Mg–Ni–Ti ternary hydrogen storage alloys for Ni-MH batteries
TL;DR: In this paper, the cycle life improvement of the Mg 0.5 Ni electrode can be attributed to the formation of TiO 2 which limits Mg(OH) 2 formation.

Structural and thermodynamic properties of heavily mechanically deformed Ru and AlRu
TL;DR: In this paper, the authors report on high energy ball milling of Ru and AlRu and show that the deformation results in a drastic decrease of the crystal size to a nanometer scale and an increase of atomic-level strain.
Journal ArticleDOI
Glass-forming range in mechanically alloyed Ni-Zr and the influence of the milling intensity
TL;DR: In this article, the effect of milling intensity on the glass formation has been studied for the first time, showing that deep eutectics do not play any role, contrary to amorphization by melt spinning.
Journal ArticleDOI
A mathematical and experimental dynamical phase diagram for ball-milled Ni10Zr7
TL;DR: Based on a deeper mathematical treatment of the process taking place in a planetary ball mill and experimental results concerning the ball-milled end product of the Ni 10 Zr 7 compound, Wang et al. as discussed by the authors proved that neither the shock frequency nor the shock energy separately governs the ball milled end products as assumed previously.
Journal ArticleDOI
Effects of Ti on the cycle life of amorphous MgNi-based alloy prepared by ball milling
TL;DR: In this article, the degradation mechanism of amorphous MgNi alloys is suppressed by replacing the magnesium oxide layer on the surface with titanium oxide layer, which is a critical factor for improvement of cycle life.
Journal ArticleDOI
Interdiffusion during the formation of amorphous alloys by mechanical alloying
TL;DR: Based on the concentration variation of Ni in Zr as a function of the milling time and using a simple interdiffusion model, an effective local temperature at the collision site is estimated.
